براغي رأس سداسي M6-1 × 80 مم | فولاذ فئة 10.9 مطلي بالزنك | سنون جزئية (150 / عبوة)

Used a few of these for mounting a motor bracket on a workbench, and the 10.9 grade steel feels notably tougher than the standard hardware I had lying around. The hex head gripped cleanly with a socket, no stripping at all.

Put together my garage shelving with these and the partial threading really helped the bolts seat cleanly without binding. They feel solid in the wrench, no stripped heads.

Used these for mounting some heavy brackets in my workshop, and the 10.9 grade steel handled the torque without stripping. The zinc plating seems solid so far, no rust after a few weeks in a slightly damp garage.
